Definitions
- the invention relates to a semiconductor integrated circuit with a semiconductor memory arrangement embedded in a circuit chip and with an interface circuit that is used to connect and transmission of data and control signals between the Semiconductor memory arrangement and a circuit periphery surrounding it set up and on the same semiconductor chip is integrated.
- ASICs Integrated semiconductor circuits that according to user requirements
- the maximum bit width that can currently be implemented is one Cell array of an embedded semiconductor memory device for example 64 bit.
- semiconductor chip 1 has an integrated in a semiconductor chip 1
- Semiconductor circuit an embedded semiconductor memory device or a memory array 10 with an interface circuit 2 for connecting and transmitting (not shown) Data and control signals between the semiconductor memory device 10 and a surrounding integrated on the same chip 1 Circuit periphery 11 on.
- the memory array 10 can be configured as required by the user different cell fields in terms of size and organization exhibit.
- the memory array 10 in FIG. 2 contains, for example, four 2 Mbit cell fields 10 1 , 10 2 , 10 3 and 10 4 with a generator block 12 and a secondary sense amplifier and decoding logic block 13.
- Fig. 3 are of a cell array of an embedded semiconductor memory device 10 according to FIG. 2 only the primary sense amplifier 20 indicated by hatched lines.
- the primary sense amplifiers 20 carry sense lines an interface circuit designed according to the invention as a standard interface 2 to secondary sense amplifiers 30, which are those of amplify data read out from the semiconductor memory device and feed a column decoder 40, which in the in Fig. 3rd example shown 64 contains read data output pads A1 - A64.
- the standard interface 2 is for the largest Bit width, 64 bits in the example, of the embedded semiconductor memory arrangement 10 designed.
- the standard interface points a switch arrangement (not shown) with which unused Bits if a smaller bit width of the semiconductor memory device 10 to be realized can be switched off.
- the cell array is thus the semiconductor memory arrangement 10 always the same size and through the implementation of the standard interface with the largest bit width only need the number of Column decoder in decoder block 40 and the number of secondary sense amplifiers be adjusted in the amplifier block 30.
